over operating free-air temperature range (unless otherwise noted) (1) DAC8830, DAC8831 UNIT DAC8830 DAC8831 SLAS449B–FEBRUARY 2005–REVISED APRIL 2006 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

The DAC8831 output is bipolar (±V REF ) when it connects to an external buffer (see the Bipolar Output Operation section for details). (2) Slew Rate is measure from 10% to 90% of transition when the output changes from 0 to full scale. (3) Digital feedthrough is defined as the impulse injected into the analog output from the digital input. It is measured when the DAC output does not change; CS is held high, while SCLK and DIN signals are toggled. LSB LSB Submit Documentation Feedback 3
